Developmental explanations of delinquent behavior among siblings: Common factor vs. transmission mechanisms

We compare the statistical fit of two developmental explanations of delinquent behavior using longitudinal sibling data. The transmission effects model relates future delinquency to prior delinquency, delayed sibling effects, and unique environment. The common-factor effects model adds to these influences a latent variable representing persistent causes shared by siblings. These two models were fit to longitudinal data on 470 sibling pairs interviewed on three occasions. The common-factor effects model fit the data more closely than the transmission model. Nonmutually exclusive interpretations of the common effects model include (a) personality dispositions and (b) unchanging aspects of the social environment such as concurrent sibling effects and siblings' common friends.     

High Risk Behaviors Among Victims of Sibling Violence

Despite the fact that sibling abuse has been documented as the most common form of intrafamilial abuse, it has been largely overlooked. Using data from the 2007 Delaware Secondary School Student Survey (N = 8,122), this paper focuses on four objectives: to estimate prevalence of sibling abuse, examine the relationship between sibling violence and high risk behaviors such as substance use, delinquency and aggression, explore the interplay of sibling abuse and other forms of family violence in predicting high risk behaviors, and test theory. Results suggest that sibling violence occurs more frequently than other forms of child abuse. Results also confirm that sibling violence is significantly related to substance use, delinquency, and aggression. These effects remain significant after controlling for other forms of family violence. The data suggest support for feminist theory and social learning theory.     

PUBERTAL DEVELOPMENT,SOCIAL FACTORS,AND DELINQUENCY AMONG ADOLESCENT BOYS*

The National Longitudinal Study of Adolescent Health is used to examine the relationship between pubertal development and delinquency among boys (grades 7–9). We find strong positive relationships between pubertal development and violence, on one hand, and property crimes, drug use, and precocious sexual behavior on the other. However, we find no evidence that these effects are due to the effects of puberty on risk‐taking, maladjustment, dominance behavior, or autonomous behavior. We do find evidence that pubertal development interacts with social factors—mature boys are more strongly influenced by delinquent friends. Pubertal development also has stronger effects on the delinquency of boys who are academically successful and thus are generally disinclined to engage in delinquency.     

The Influence of Dating Relationships on Friendship Networks,Identity Development,and Delinquency

Prior research has documented general associations between dating and delinquency, but little is known about the specific ways in which heterosexual experiences influence levels of delinquency involvement and substance use. In the current study, we hypothesize that an adolescent's level of effort and involvement in heterosexual relationships play a significant role in forming the types of friendship networks and views of self that influence the likelihood of delinquency involvement and substance use. Analyses based on a longitudinal sample of adolescent youth (n = 1,090) show that high levels of dating effort and involvement with multiple partners significantly increases unstructured and delinquent peer contacts, and influences self‐views as troublemaker. These broader peer contexts and related self‐views, in turn, mediate the path between dating relationships, self‐reported delinquency, and substance use. Findings also document moderation effects: among those youths who have developed a troublemaker identity and who associate with delinquent peers, dating heightens the risk for delinquent involvement. In contrast, among those individuals who have largely rejected the troublemaker identity and who do not associate with delinquent friends, dating relationships may confer a neutral or even protective benefit. The analyses further explore the role of gender and the delinquency of the romantic partner.     

SIBLING DEVIANCE: IN THE SHADOWS OF MUTUAL AND UNIQUE FRIENDSHIP EFFECTS?*

Drawing on a large sample of genetically related pairs of adolescents from the Add Health, we examine the influence of sibling deviance on adolescents' participation in minor deviance compared to the influence received from mutual friends (i.e., friends shared between siblings) and influence from unique friends (i.e., friends unique to each sibling). Multivariate analyses that control for genetic relatedness using DeFries‐Fulker regression (1985) indicate that after aspects of the shared and non‐shared environment of siblings are accounted for, the heritability effect, capturing genetic relatedness in sibling deviance, is no longer significantly associated with deviance. The deviance of siblings' unique friends accounts for a large portion of the heritability effect of sibling deviance.     

Peer pressure and adolescent substance use

Peer influence is regarded as one of the strongest determinants of juvenile delinquency and particularly adolescent substance use. A commonly held view is that social pressure from friends to use drugs and alcohol is a major contributor to substance use. Yet the notion of peer pressure, implied by the association between peer-group associations and drug behavior, is seldom tested empirically. As a crucial test of the group pressure model, this research examines the role of peer pressure in mediating the effect of differential association on individual use. Moreover, few studies examine the nature of the relationship between peers and substance use as it relates to the processes leading toand from use. Drawing on differential association and social learning theories, our research specifies the social processes (socialization, group pressure, social selection, and rationalization) which dictate particular causal pathways leading to and from substance use and then estimates the reciprocal influences among differential association, social pressure from peers, attitudes favorable toward substance use, and individual use. Using the 1977–1979 National Youth Survey panel data, we estimate a covariance structural equation model allowing for correlated measurement error. In the cross-sectional analyses, we find no main effects of overt peer pressure on substance use. Estimation of the reciprocal effects model also reveals that overt peer pressure does not significantly influence substance use and does not mediate the effect of differential association. Instead, the influences of socialization, social selection, and rationalization play significant roles in understanding substance use.An earlier version of this paper was presented at the 1994 American Society of Criminology meetings in Miami, Florida.     

Genetic and Environmental Influences on Delinquency: DF Analysis of NLSY Kinship Data

This paper follows earlier research (Rowe et al., 1992) in evaluating the basis of family influences on adolescent delinquent behavior. Delinquency is measured in a number of different ways to account for important theoretical distinctions that exist in the delinquency literature. We use recently identified kinship structure in a large national data set—the National Longitudinal Survey of Youth—to estimate genetic and shared environmental influences on self-reported delinquency scores. Our analytic model is based on DF analysis, a regression procedure used to estimate parameters reflecting genetic and environmental influence. Results suggest a consistent and moderate genetic basis to sibling similarity in delinquency and little evidence of a shared environmental basis. A large amount of variance is attributable to nonshared influences and/or measurement error. Our findings suggest that the search for environmental influences on adolescent delinquency should focus on those that are not shared by siblings.     

Poor parenting and antisocial behavior among homeless young adults: links to dating violence perpetration and victimization

Though research has examined risk factors associated with street victimization among homeless young people, little is known about dating violence experiences among this group. Given homeless youths' elevated rates of child maltreatment, it is likely that they are at high risk for dating violence. As such, the current study examined the association between child maltreatment and parental warmth with dating violence perpetration and victimization through substance use and delinquency among a sample of 172 homeless males and females. Results from path analysis revealed that physical abuse, sexual abuse, and neglect were all significant correlates of both substance use and delinquency, whereas lack of parental warmth was only associated with substance use. Neglect and substance use had direct effects on dating violence and substance use and was found to mediate the relationship between physical abuse and dating violence. Finally, females, older youth, and non-Whites had significantly higher levels of dating violence compared with their counterparts.     

EARLY LIFE RISKS,ANTISOCIAL TENDENCIES,AND PRETEEN DELINQUENCY

Early age‐of‐onset delinquency and substance use confer a major risk for continued criminality, alcohol and drug abuse, and other serious difficulties throughout the life course. Our objective is to examine the developmental roots of preteen delinquency and substance use. By using nationally representative longitudinal data from the UK Millennium Cohort Study (N= 13,221), we examine the influence of early childhood developmental and family risks on latent pathways of antisocial tendencies from 3 to 7 years of age, and the influence of those pathways on property crime and substance use by 11 years of age. We identified a normative, nonantisocial pathway; a pathway marked by oppositional behavior and fighting; a pathway marked by impulsivity and inattention; and a rare pathway characterized by a wide range of antisocial tendencies. Children with developmental and family risks that emerged by 3 years of age—specifically difficult infant temperament, low cognitive ability, weak parental closeness, and disadvantaged family background—face increased odds of antisocial tendencies. Minimal overlap is found between the risk factors for early antisocial tendencies and those for preteen delinquency. Children on an antisocial pathway are more likely to engage in preteen delinquency and substance use by 11 years of age even after accounting for early life risk factors.     

PEER SIMILARITY IN DELINQUENCY FOR DIFFERENT TYPES OF FRIENDS: A COMPARISON USING TWO MEASUREMENT METHODS*

Peer similarity in delinquency has been studied extensively. But basic questions remain about measuring peer delinquency and how important the nature of relationships with delinquent peers is. This article uses data from the NSCR School Project, which has collected unusually detailed information about delinquent peers and the social networks of adolescents. We examine differences in the roles of regular friends and best friends with regard to peer similarity in delinquent behavior. We also contrast two methods of measuring peer delinquency: the conventional one of asking respondents about their peers, and the social network method, by which peers report about themselves. The results show that respondents can have best and regular friends who differ in their degree of delinquency, and that the association between respondent and peer delinquency does not differ much between friends and best friends. At the same time, our results suggest that both types of peers influence the level of respondent delinquency. Measures based on the direct network method resulted in higher estimates of peer delinquency, but in lower estimates of the association between respondent and peer delinquency.     

A Network Analysis of Factors Leading Adolescents to Befriend Substance-Using Peers

Objective

Our interest is in the systematic network selection processes that lead adolescents into friendships with substance-using peers. Theory suggests that adolescents with certain risk factors (i.e., weak attachments to conventional society and low self-control) are more likely to select substance-using friends. Our goal is to evaluate whether adolescents with particular risk factors have a greater risk for befriending substance-using peers, while controlling for common network selection processes that can produce the same friendship pattern. These selection processes are important as they help to set the stage for later peer influence on substance use.

Methods

We use a Stochastic Actor-Oriented Model to examine network change among 1373 adolescents from the National Longitudinal Study of Adolescent Health. We test whether low self-control and indicators of weak attachments (to family, school, and religion) predict selecting friends engaged in alcohol, tobacco, and marijuana use.

Results

We find widespread evidence of the hypothesized friendship pattern within adolescent friendship networks. In most cases this pattern is a product of selection based on the risk factor and substance use, and not attributable to other selection mechanisms.

Conclusions

We highlight the need to broaden the study of delinquency to account for how adolescents come to acquire friends who may be negative sources of peer influence. We offer theoretical and methodological insight to this question, ultimately finding that only in limited cases are adolescents with particular risk factors more likely to select friends involved in substance use. We discuss implications for theory and future investigations of peer influence.

     

GENDER,FRIENDSHIP NETWORKS,AND DELINQUENCY: A DYNAMIC NETWORK APPROACH

Researchers have examined selection and influence processes in shaping delinquency similarity among friends, but little is known about the role of gender in moderating these relationships. Our objective is to examine differences between adolescent boys and girls regarding delinquency‐based selection and influence processes. Using longitudinal network data from adolescents attending two large schools in AddHealth (N = 1,857) and stochastic actor‐oriented models, we evaluate whether girls are influenced to a greater degree by friends’ violence or delinquency than boys (influence hypothesis) and whether girls are more likely to select friends based on violent or delinquent behavior than boys (selection hypothesis). The results indicate that girls are more likely than boys to be influenced by their friends’ involvement in violence. Although a similar pattern emerges for nonviolent delinquency, the gender differences are not significant. Some evidence shows that boys are influenced toward increasing their violence or delinquency when exposed to more delinquent or violent friends but are immune to reducing their violence or delinquency when associating with less violent or delinquent friends. In terms of selection dynamics, although both boys and girls have a tendency to select friends based on friends’ behavior, girls have a stronger tendency to do so, suggesting that among girls, friends’ involvement in violence or delinquency is an especially decisive factor for determining friendship ties.     

EXPLAINING THE RELATIONSHIP BETWEEN EMPLOYMENT AND JUVENILE DELINQUENCY*

Most criminological theories predict an inverse relationship between employment and crime, but teenagers' involvement in paid work during the school year is correlated positively with delinquency and substance use. Whether the work–delinquency association is causal or spurious has been debated for a long time. This study estimates the effect of paid work on juvenile delinquency using longitudinal data from the national Monitoring the Future project. We address issues of spuriousness by using a two-level hierarchical model to estimate the relationships of within-individual changes in juvenile delinquency and substance use to those in paid work and other explanatory variables. We also disentangle the effects of actual employment from the preferences for employment to provide insight about the likely role of time-varying selection factors tied to employment, delinquency, school engagement, and leisure activities. Whereas causal effects of employment would produce differences based on whether and how many hours respondents worked, we found significantly higher rates of crime and substance use among nonemployed youth who preferred intensive versus moderate work. Our findings suggest the relationship between high-intensity work and delinquency results from preexisting factors that lead youth to desire varying levels of employment.     

Reconsidering Peer Influences on Delinquency: Do Less Proximate Contacts Matter?

Much research on adolescent delinquency pivots on the notion of peer influence. The peer effect that is typically employed emphasizes the transmission of behaviors and attitudes between adolescents who are directly linked. In this paper, we argue that to rely solely on those direct social ties to capture peer influence oversimplifies the realities of adolescent society. We use data from the National Longitudinal Study of Adolescent Health to show that indirect peer relations can exercise independent influences on adolescent delinquency. Adolescents actively draw on the examples of friends of friends, and even more distal peers, as they develop their repertoires of action and identity. We argue, however, that this behavior actually reflects adolescents’ ongoing struggle to impress their closest friends and to preserve their social circle. Indeed, the extent to which adolescents are willing to model the behavior of indirect contacts seems to decline as that behavior becomes more dissimilar from that of their close friends. Our findings dovetail with an account of the adolescent as a rational actor who struggles for social acceptance in a complex peer environment which offers conflicting behavioral models.

THE FAMILIAL TRANSMISSION OF CRIMINAL CONVICTIONS*

This article examines the familial transmission of criminal convictions in families in the Cambridge Study in Delinquent Development. Our main analyses focus on the 344 families in the Cambridge Study with two or more children. Criminal convictions were highly familial because convictions in a parent increased the risk of convictions in a child. Correlations between siblings were stronger in same-sex siblings (.45 to .50) than in opposite-sex ones (.27). Sibling correlations did not vary by birth order. Convictions of mothers and father correlated .55. Parent-child correlations were about the same as within-generation correlations between siblings. LISREL models were used to assess whether the effect of parental convictions on child convictions was direct or mediated through the quality of the family environment (i.e., supervision. child rearing, and family size). The best fitting LISREL models suggested a direct effect of parental convictions on child convictions, without any mediation by family environment. These data on fill biological siblings, however, did not permit separate estimation of family environmental versus genetic effects. One environmental effect appeared, however—a socialization effect among siblings; in families with three sons, there appeared to be mutual influence of one sibling on another. Also, regression models based on the boys suggested that family environmental variables did add to parental criminality.     

DECOMPOSING THE PEER EFFECT ON ADOLESCENT SUBSTANCE USE: MEDIATION,NONLINEARITY, AND DIFFERENTIAL NONLINEARITY*

Although the correlation between peer delinquency and delinquency is one of the most consistently demonstrated findings in delinquency research, researchers have focused primarily on the direct, linear, and additive effects of peers in statistical models, rather than on empirically modeling mediating, nonlinear, and moderating processes that are specified by theory. To address these issues, we measure respondent delinquency and peer delinquency with illegal substance use and then decompose the effect of peer substance use on self‐reported substance use. Logistic hierarchical models on a sample of adolescents from the Project on Human Development in Chicago Neighborhoods (PHDCN) indicate that the effect of peer substance use on self‐reported substance use is partially mediated by perceptions of the health risks of substance use. In addition, the direct statistical effect of peers is nonlinear: On average, the peer effect decreases at higher values of peer substance use, which is consistent with a “saturation” effect. We also find that the functional form of the peer substance use/substance use relationship is dependent on the neighborhood context. In neighborhoods with more opportunities for crime, the peer effect is initially strong but decreases as peer substance use increases, which is consistent with a saturation effect. Conversely, in neighborhoods with fewer opportunities for crime, the effect of peers is initially small, but as delinquent peer associations increase, the peer effect increases multiplicatively.     

Treating Adult Survivors of Sibling Sexual Abuse: A Relational Strengths-Based Approach

Sibling sexual abuse is a far more common manifestation of family violence than is often recognized. Researchers agree that it has received less attention than other forms of child abuse trauma despite the fact that good evidence suggests it is no less injurious than child sexual abuse when a parent or other adult is the perpetrator. This paper describes a relational, strengths-based approach to psychotherapy with adult survivors of sibling sexual abuse guided by trauma-informed principles. Cultural considerations are discussed as well as an overview of the clinical research on sibling sexual abuse and its harmful effects. Clinical case material, treatment strategies and a case illustration demonstrate therapeutic principles of the approach in action.     

DELINQUENT PEERS IN CONTEXT: A LONGITUDINAL NETWORK ANALYSIS OF SELECTION AND INFLUENCE EFFECTS*

In this article, longitudinal social network data are analyzed to get a better understanding of the interplay between delinquent peers and delinquent behavior. These data contain detailed information about the social networks of secondary school students from the same grade, their delinquent behavior, and many relevant correlates of network formation and delinquency. To distinguish selection and influence processes, a method (Simulation Investigation for Empirical Network Analyses, SIENA) is used in which network formation and changes in delinquency are simulated simultaneously within the context of other network processes and correlates of delinquency. The data and the method used make it possible to investigate an unusually wide array of effects on peer selection and delinquent behavior. The results indicate that similarity in delinquency has no significant effect on the selection of school friends when other network dynamics are taken into account. However, the average delinquency level of someone's friends in the school network does have a significant, although relatively small, effect on delinquent behavior of the respondents, beyond significant effects of changes in the level of self‐control and morality. Another peer‐related change, leaving or joining informal street‐oriented youth groups, also appears to have a substantial effect on changes in delinquency.     

Parental and Others’ Responses to Physical Sibling Violence: a Descriptive Analysis of Victims’ Retrospective Accounts

Although sibling abuse may be the most common form of family violence, relatively few studies have been conducted on this topic. The current exploratory study addressed this gap in the literature through analyses of thematic categories in sibling abuse narratives gathered from an online survey of sibling violence victims. All data was collected via an online survey. Participants who reported being victimized by physical sibling violence were asked to reflect on how others—family members, professionals, and friends—responded to knowledge of the abuse. Results demonstrate a need for general education about sibling violence, particularly for parents who might minimize or normalize their children’s violent conflicts. Additionally, parents need assistance in developing appropriate responses to sibling violence, as participants often perceived their parents to be ineffective at preventing or stopping the abuse. Finally, this study suggests that negative or unhelpful parental responses can be as harmful as the sibling violence itself.     

SIBLING RESEMBLANCE IN JUVENILE DELINQUENCY: FINDINGS FROM THE NATIONAL YOUTH SURVEY*

Analyses based on individual- and family-level self-report data indicate that (1) delinquency incidents are disproportionately concentrated among households with adolescents, (2) families do not specialize in delinquency by producing certain types of offenders, and (3) adolescent levels of delinquency are predicted equally as well by the offending of an older sibling. the offending of a younger sibling, or by the average level of offending among all other adolescents in the household. Three sets of family characteristics (socioeconomic status, composition, and functioning) are used in multivariate analyses to examine the association among sibling delinquency levels. while sibling composition and family functioning are significant predictors of adolescent delinquency, only family functioning accounts for a small proportion of sibling resemblance in offending. These analyses add to the growing body of research that suggests that sibling similarity in delinquency requires additional consideration in theoretical and empirical investigations of juvenile offending.
